Write the brewery exterior list before anyone estimates hands
Comparing labor for cleaning the outsides of brewery equipment fails at one point: each bidder, and each of the buyer's own supervisors, pictures a different job. One supplier assumes a seasoned operator with a pressure lance. One crew leader assumes a hot-surface wipe-down at the end of a shift. The written scope list is what makes those two pictures comparable, and it costs nothing but an hour with someone who actually walks the brew floor. It is also where an unqualified access claim gets cut, because the site's own cleaning pages stop at equipment exteriors and describe no work at height or inside vessels.
Build the list one surface group at a time, in the order the crew reaches them during a real break between batches. Vessel and tank outsides, shell, dished top, skirt and the fittings bolted to them; the frames, platforms and handrails that carry people to those shells; pipe runs, valves and their insulation jackets; the casings of pumps, conveyors and heat exchangers; the panels of the control cabinets that stand in the same bay; floors and gully surrounds immediately under the work. For each row the buyer writes three things in plain words: what sits there, what is normally on it, and what has to stay undisturbed while it is cleaned. The deposit column matters more than the size column, because a fresh spill and a week-old residue are not the same task, and the difference lands directly in the labor line rather than in the equipment line.
Two boundaries belong in that same sheet, written as plainly as the surface rows. Anything inside the equipment is out of scope: tank interiors, vessel internals, process lines and their cleaning-in-place duty. Anything that needs purpose-built access is either written as excluded or handed to a separate, named responsible party. The buyer does not have to decide those questions alone, but the answer must be on the page before prices and hands arrive, otherwise the comparison collapses into arguments about what was included.
Turn the list into a task chain and price the brewery constraints inside it
Hands are counted per task, not per surface. Read the scope list as a sequence: clearing the aisle and protecting what sits nearby; loosening the deposit; lifting it off the surface; moving the loosened material away; drying; recording what was done; inspecting and releasing the area for the next batch. Each task gets its own row, and each row gets two marks. The first is whether the task can be done by one person or genuinely needs a second pair of hands, which in this kind of area is usually decided by awkward geometry, a shield that has to be held, or a hose that has to be moved around a frame. The second is whether the task can run while the neighbour is still working, or whether it stops the neighbour.
That second mark is where brewery areas behave differently from a workshop floor, and it is what most estimates lose. Wet work over an open process area is scheduled around production, so a real share of the labor bill is waiting: waiting for the line to be free, waiting for a surface to cool enough to touch, waiting for permission to bring water into a wet room. Some of it is a second shift, and a second shift brings a supervisor with it. Write those waits as tasks in their own right. An estimate that counts only the minutes of contact work will always look cheaper than the invoice that finally arrives, and it can never be compared with another estimate because nobody knows what each of them assumed about the calendar.
The remaining brewery-specific labor sits outside the cleaning task chain, and it is often the largest surprise on the comparison. A heat source in the room needs electricity, an inlet and a drain close to the work, and every one of those is a walk that somebody repeats for the whole job. Run-off from cleaning above open drainage is a waste stream somebody has to handle and dispose of, not a detail that disappears. Power leads and hoses crossing a wet tiled aisle need routing, and in a food-contact area the crew's footwear, coats and hands are part of the shift's hygiene routine, which means changing and washing time is real work and should be counted as work. Ask the site's own maintenance and quality people what these items take before the enquiry goes out; they know the answers, and a bidder will not.
Run one written trial and hand every bidder the same record
The published pages on this site describe cleaning duty and machine categories; they publish no labor figures, no crew sizes and no cleaning rates, so a buyer cannot audit a supplier's estimate against them and neither party should try. What the buyer can build is one honest measurement on their own site. Choose one unit from the scope list, photograph the surface as found, and clean it exactly as the scope list describes, with one supervisor holding a clipboard. Record start and stop for each task in the chain, note every wait, note every step the crew had to repeat because a drain or a cable run was in the wrong place, and judge the result only after the surface is dry, by someone who never held the tool. A single marked strip, judged cold and dry by a fresh pair of eyes, is worth more than a brochure claim.
That record becomes the comparison instrument. Send it, unchanged, to every bidder along with the same scope list, the same exclusions and the same three questions: which tasks in the chain do you expect to run with one person, which with two, and what has to be true on site before your crew can work without waiting. Ask each of them to answer in the same row labels you used. A bidder who cannot break their answer down into those rows has quoted a hope, not a plan. Comparing answers written against one shared record is the only labor comparison that survives contact with the invoice.
Then keep the unit of comparison honest. A single clean shell tells you nothing about a round that has to cover a whole set of vessels in the same break, and a round tells you nothing about a year of those rounds. Reprice the winning answer for the whole set, then for the recurring pattern the site actually runs, and check whether the recurring work is cheaper done inside the break or outside production. That is where a fixed installation earns a place beside a mobile one: Fixed Steam Cleaning Machine PowerDe HW02 is a fixed unit, and the published description of a fixed installation puts water, drainage and power at one point rather than walked across the room. Whether that suits this site is a question the buyer answers against their own floor plan and their own shift calendar, not against a datasheet. Anyone comparing their own duty against the wider range starts at PowerDe cleaning equipment, and when the surfaces do not match any published category, customized steam cleaning equipment is the route for putting the scope list in front of the supplier before anything is quoted.
None of this requires a number from the supplier first. It requires a written list, a task chain, one measured trial and one shared record. Teams that do those four things compare labor; teams that skip them compare adjectives.
